Application {iled February 24, 1899. Serial No. 706,703. (No model.)

To all whom it may concern:

Beit known that we, ALEXANDER R. DEMP- STER and WILLIAM D. RINEHART,citizens of the United States of America, and resid ents of Des Moines,in the county of Polk and State of Iowa, have invented certain new anduseful Improvements in Tank-Heaters, of which the following is aspecification.

The object of this invention is to provide an improved separable andpivoted cover for a tank-heater.

Our invention consists in the construction, arrangement, and combinationof elements hereinafter set forth, pointed out in our claims, andillustrated by the accompanying drawings, in which- Figure 1 is anelevation ot' the complete de- Fig. 2 is aplan of the complete device.Fig. 3 is a vertical section of the device on the indicated line 3 3 ofFig. 2. Fig. 4 is a horizontal section of the device on the indicatedline 4 4of Fig. 1. Figs. 5 and 6 are detail views of the means employedto connect .the sections of the cover. Fig. 7 is a detail illustratingthe means employed to connect the sections of the cover to theheater-body.

In the construction of the device as shown the numeral 10 designates thebottom of a drinking-trough 'on which the heater rests. The heater isformed with a bottom 11, preferably circular in plan View, and acylindrical body 12, i'ixed to the bottom at its lower edge and risingtherefrom. The upper edge of the cylindrical body 12 is wired or turned.A basket grate 13, provided with a bail 14 and supported by legs 15,formed on and extending downwardly from the grate, is positioned in andon the upper face of the bottom of the heater and is removableandreplaceable through the top of the cylindrical body. The grate 15 isformed with a semicircular notch 16 at a given point in its periphery,and a' end of the draft-pipe 17 is split upwardly a little distance andcut transversely at the upper end of the slit in order that the sidev ofthe pipe may be opened toward and beneath the grate 13 to provide adraft-vent to the space below the grate. are mounted on and fixed to theupper edge of the body 12 diametrically opposite each other and areaperture-d vertically in their outwardly extending horizontal portions.Rods 22 23 are vertically positioned through the apertures of the ears20 21, which rods extend downwardly along the outside of the body 12through the bottom 10 of the tank or trough and are secured by nuts ontheir lower ends, thereby binding and securing the heater rigidly in thetrough.

The cover of the heater is formed in two sections 24 25 of cast metaland similar size and shape. The complete cover is approximately circularin plan view and is diametrically divided to form the sections, and atlange 26 on the section 25 overlaps the meeting edge of the section 24.Ears 27 28 are formed on the sections 24 25 of the cover, respectively,the ear 28 above the ear 27, and are apertured vertically. The sectionsof the cover rest upon the wired or turned upper edge of the body 12,and the rod 22 traverses the apertures in the ears 27 28, forming apivot for the sections of the cover.v A nut 29 is xed to the upper endportion of the rod 22 and impinges the upper face of the ear 28, thusholding the ears of the sections of the cover in close relations to theear 2O on the body. Lugs 30 3l are formed on the sections of the coverat points thereon diametrically oppo-v site the ears 27 28 and extenddownwardly and toward each other beneath the outwardly extendinghorizontal portion of the ear 21. The function of the lugs 30,31 is toengage beneath and with the ear 2l and hold the cover-sections closelyto the upper edge of the body 12. An ear 32 is formed on and extendsupwardly from the cover-section 24 adjacent the lug 30 and is formedwith a latere ally-projecting portion or stud 32, slightly reduced inthickness at the jointure thereof to the ear. An ear 33 is formed on andrises from the coversection 25 adjacent the lug 3l,

Ears 20 21 of angle form IOO and a hook-latch 34 is pivoted at one endon said ear. The free end of the hook-latch is notched on the lowerportion to form a fork, so shaped as to en gage,when manually placed,the reduced portion of the stud 32 on the ear 32 and securely connectthe cover-sections. A projection 34"L is formed on and pro jectsupwardly and forwardly from the free end of the hook-latch, by means ofwhich the latch may be engaged and lifted from the stud 32 by the handof the operator ora tool employed thereby. A draft-port 35 is formed inthe cover-section 25 immediately above the upper end of the draft-pipe17, and a damper 36 is pivoted on said cover-section and so located andarranged as to close said draft-port when lnannally placed. A smokeport37 is formed in the cover-section 24, and a {iange 3S is formed on saidsection and rises therefrom circumferentially of the port. A smoke-tlue39 is mounted on and rises from the flange 3S and is provided with acollar 40, embracing its upper end portion. The collar 40 is employed toengage and clamp a section of Wire-cloth 41 to the upper end of thesmoke-Hue, said cloth crossing and forming a screen or cap for the Hue.The lower end portions of the fine 39 and flange 3S are apertured toadmit split keys 42 43, whereby the flue is connected to the flange.

The heater is opened for firing, cleaning, repairing, or the removal orreplacement of the grate by releasing the latch 34 and swinging one orboth of the cover-sections laterally on the pivot formed by the rod 22.

XVe claim as our invention- 1. In a tank-heater the combination of thebody, the ears thereon, the rods traversing the ears and arranged forattachment to a supporting-trough, the cover formed in two sections andpivoted on one of said rods, the lugs on the coversections engaging oneof the ears and the latch connecting the cover-sections.

2. In a tank-heater, the combination of the body, the ears 20, 21,thereon, the rods traversing the ears and arranged for attachment to asupporting-trough, the cover formed in two sections, ears 27 28, on thecover-sections and located vabove and in alinement with the ear 2O andapertured for pivoting on the rod traversing said ear 20, the ange onone of the cover-sections overlapping the adjacent edge of the othercover-section, the lugs on the cover-sections opposite the ears 27, 2S,and engaging beneath the ear 2l, and the latch connecting thecover-sections.

3. In a tank-heater, the combination of the body, the ears 20, 21,thereon, the rods traversing the ears and arranged for attachment to asnpporting-trough, the cover formed in two sections and pivoted on therod traversing the ear 20, the lugs on the cover-sections engagingbeneath the ear 21, an ear 32 formed on and rising from one of thecover-sections adjacent the ear 21, a stud 32 formed on and laterallyprojecting from the ear 32 and slightly reduced in thickness at thepoint of jointure to the ear 32, an ear on the other cover-section and ahook-latch 34 pivotcd on the ear 33 and notched to embrace the reducedportion of the stud 32, whereby the cover-sections are connected.
